Answer:
Many biofilm-specific phenotypes are controlled by "quorum sensing." This system allows bacteria to regulate gene expression according to the concentration of <u>bacteria</u>.
Explanation:
Quorum sensing is basically a process which depends upon the <u>density dependent communication </u>of bacteria. Higher the number of bacteria, more will be the communication. Example of quorum sensing is biofilms which grow on various surfaces.
Some auto-inducers like peptides and N-acyl homoserine lactone are produced by bacteria during this process which in turn activate some transcription factors to cause gene expression.
In bacteria, it mainly serves the purpose of bioluminescence, sporulation and nitrogen fixation.
Answer: The DNA
Explanation: DNA is the only part of the cell that can mutate. That DNA could cause other cell parts to have mutations further down the road, though.
If you mean what part of the cell cycle, then it is interphase, while DNA is replicating.
Answer:
Prophase, Prometaphase, and Metaphase
Answer:
B. In cancer cells, too little apoptosis occurs, resulting in malignant cells that will not undergo programmed cell death.
